Have some logs that need delivered through rough track, steep grades, and tight corners? Our new Class A Climax will get them to the mill!

Power for this model comes from a Tomytec TM-04 chassis, which is 4 wheel drive, 8 wheel pickup, and a traction tire on one drive wheel. The parts are hollow to easily add the weight of your choice. We prefer "Liquid Gravity" by Deluxe Materials.

The modeler can decide what type of materials to use for the sides, and what details to add, but our test model was built up with .040" square styrene rod for the roof and side supports, and .020" styrene grooved sheet for the sides, along with some .060" L angle and bits and pieces. The piping and rear railing is made from .015" phosphor bronze wire, with spots already laid out on the boiler for the sand lines and pipes. The bell and whistle assembly are brass castings from the parts bin.

Printed parts (roof not shown)

Printed parts seen here. These are Frosted Extreme Detail, which makes finishing the parts much easier, as the layers are finer. Cleaning and some finish sanding is required prior to painting the Frosted Detail plastics. The frame fits snugly onto the Tomytec Chassis, no glue or screws required, allowing for easy maintenance. The side frames press fit into the power trucks. Glue is not required or recommended.

1/8" square brass rod from K&S metals fits nicely between the Tomytec chassis and the kit frame. It's not required for assembly, but adds a bunch of weight low on the model, which improves performance. use epoxy or CA glue to attach these weights to the 3D printed parts, not the Tomytec chassis.

The stake pockets are already hollow, allowing easy fit of the roof and side supports. The roof has matching square holes to speed things up, just cut your posts to length, and glue in place. Some minor sanding might be required to get the .040" square stock to fit, test fit before gluing!

The wood load is BBQ skewers, cut with old rail nippers... they're hiding more brass square stock for weights. There is enough room in the center by the chassis motor for even MORE weight if desired, we opted to leave this space available for crew figures and other details. These photos show off the insane amount of detail that can be achieved when using Frosted Extreme Detail. The truck springs, for instance, are actual coils of 3D printed plastic. When painted and weathered, you can't tell they're not real!

The CLIMAX kit looks to be outstanding, but the ad fails to note which particular TOMYTEC powered(?) chassis fits the kit(?). There are quite a few different sizes of TOMYTEC powered chassis listed on eBAY, so the size that is used for this kit it very important when thinking about purchasing all the correct components.
